Azure IoT Hub is a REST API-based cloud service targeted at enterprise customers that enables secure, bi-directional communication between millions of devices and a partitioned Azure service.
Note
This article provides steps about how to delete personal data from the device or service and can be used to support your obligations under the GDPR. For general information about GDPR, see the GDPR section of the Microsoft Trust Center and the GDPR section of the Service Trust portal.
Individual devices are assigned to a device identifier (device ID) by a tenant administrator. Device data is based on the assigned device ID. Azure maintains no information and has no access to data that would allow device ID to user correlation.
Many of the devices managed in Azure IoT Hub aren't personal devices, for example an office thermostat or factory robot. Customers might, however, consider some devices to be personally identifiable and at their discretion might maintain their own asset or inventory tracking methods that tie devices to individuals. Azure IoT Hub manages and stores all data associated with devices as if it were personal data.
Tenant administrators can use either the Azure portal or the service's REST APIs to fulfill information requests by exporting or deleting data associated with a device ID.
If you use the routing feature of the Azure IoT Hub service to forward device messages to other services, then the tenant admin for each routing endpoint must perform data requests in order to complete a full request for a given device. For more information, see the reference documentation for each endpoint. For more information about supported endpoints, see IoT Hub endpoints.
If you use the Azure Event Grid integration feature of the Azure IoT Hub service, then the tenant admin must perform data requests for each subscriber of these events. For more information, see React to IoT Hub events by using Event Grid to trigger actions.
If you use the Azure Monitor integration feature of the Azure IoT Hub service to create resource logs, then the tenant admin must perform data requests against the stored logs. For more information, see Monitor Azure IoT Hub.
Deleting customer data
Tenant administrators can use the IoT devices pane of the Azure IoT Hub extension in the Azure portal to delete a device, which deletes the data associated with that device.
It's also possible to perform delete operations for devices using REST APIs. For more information, see Devices - Delete Identity.
Exporting customer data
Tenant administrators can utilize copy and paste within the IoT devices pane of the Azure IoT Hub extension in the Azure portal to export data associated with a device.
It's also possible to perform export operations for devices using REST APIs. For more information, see Devices - Get Identity.
Note
When you use Azure's enterprise services, Azure generates some information, known as system-generated logs. Some Azure IoT Hub system-generated logs aren't accessible or exportable by tenant administrators. These logs constitute factual actions conducted within the service and diagnostic data related to individual devices.
